It''s just copied to the destination and then rounded up or down. Look at this example:


float Float = 0f;
double Double = 3.1234567891234f;
Float = Double;


The maximum number of digits after the comma a float can hold is 5. When the line "Float = Double" is executed, the variable Double is truncated to 6 digits after the comma, and then rounded to 5 digits. So the value of Float becomes 3.12346.
